Wallace and Gromit were created by Nick Park, an English filmmaker and animator. He developed the characters during his time as a student at the National Film and Television School. The characters first appeared in the short film "A Grand Day Out," which was Park's graduation project. Nick Park later joined Aardman Animations, where he further developed and produced the Wallace and Gromit films and shorts. The duo has become iconic in British culture and has won multiple awards, including several Academy Awards for their films.
